Can Pyrex cookware be put in the oven? – Better

Pyrex was first produced in 1908 in the United States. It was more resistant to thermal shock than other glasses.

Today, however, the production process has changed. Where borosilicate glass was used, today soda lime is used and the product is not as strong.

Current Pyrex dishes are not resistant to thermal shock. Therefore, they would break if moved from one extreme temperature to another.

However, as with normal cooking, you can use Pyrex dishes.

Can you put Pyrex cookware in the oven?

The short answer is yes. You can put pyrex glass in the oven and use it for cooking, baking, etc.

However, you must remember that it is a bad idea to put pyrex on your cooktop. You should also not move the pyrexpan from one temperature extreme to another.

This is thermal shock and the pan will most likely break.

Pyrex temperature capability

As a general rule, you should only heat the pyrexpan or baking dish to about 400-450 F.

Anything higher than that can seriously damage its structural integrity.


Your Pyrex dish has limits. Remember that you can only move it from the refrigerator to the freezer and the oven at long intervals.

Additionally, here are some limitations of pyrex you should be aware of.

  • Preheat your oven before placing Pyrex dishes in it. Prolonged exposure to heat should be kept to a minimum.
  • Do not use pyrex on your stove or toaster oven or on a grill.
  • Allow the Pyrex to cool before returning the hot dish to the fridge or freezer.
  • Allow the pyrexpan to cool before adding liquid.
  • Do not use Pyrex to microwave popcorn or reheat foods in browning packages.
  • Do not heat empty glass containers in the microwave.
  • If you are heating cheese, oil or butter in a pyrexpan in the microwave, do not overheat. Heat for the minimum time required.


Check the warranty that comes with your Pyrex pan or bowl. There are usually clauses you can use to replace dishes or pans that have been broken by the heat of the oven.

As a precaution, you should probably check this warranty before purchasing the dish.

Precautionary measures

  • If you cook with pyrex, be sure to wear closed shoes. This ensures that no glass gets into your feet or cuts your feet if it breaks.
  • Also wear thick gloves when cleaning the glass. It protects your hands.
  • Be careful when picking up broken shards. Small shards can get into your eyes or cut your skin.
  • Throw away any food that was in the Pyrex dish when it broke. Small shards can become lodged in food. Cleaning food from splinters is useless. Every little piece of glass that enters your body is not worth the most delicious food in the world.

Remember that these precautions and guarantees only apply to Pyrex pans and dishes.

They do not apply to lids supplied with Pyrex pans. Lids can only be used for heating and microwave storage.

Safe use of Pyrex dishes

Pyrex, although a very well made tempered glass, can break easily under the right conditions. That’s why you need to know how to handle Pyrex glass professionally.

So here are some precautions you can take to make sure you don’t hurt yourself. These prevent you from being burned, cut or otherwise bruised or damaged in any way.

  • Place a baking sheet in the oven and preheat it. Then place the pie pan or pyrexpan on it. This distributes the heat throughout the pan and does not exert any pressure.
  • Do not place a hot Pyrex glass pan on a cold surface or a cold Pyrex glass pan on a hot surface. Both subject the pan to thermal shock. This will break the pan; Probably.
  • Use a hot silicone or cloth pad before placing the pyrex glass on a stovetop. This prevents it from breaking.
  • You should also use a dry kitchen towel or a wooden cutting board on a counter for the pyrexpan. This prevents the pyrexpan from slipping and falling.
  • Avoid cooking a dry dish in a glass pan. Instead, put some liquid that can cover the bottom of the dish before placing the dry food. This prevents the hot glass surface from coming into contact with the cold juices in the bowl. Therefore, a surface in between will prevent the pyrex from experiencing thermal shock.
  • Be sure to use mitts or dry towels when handling the pyrex tray. This prevents thermal shocks and the Pyrex dish or pan from breaking in your hands.
  • Make sure the pyrexpan is dry and at room temperature before washing. This is to avoid thermal shocks.
  • Do not use pyrexpans to heat dry foods in the microwave. As a general rule, do not use Pyrex pans to heat anything in the microwave. This will damage the structural integrity. Otherwise, it will likely reduce the structural integrity of the glass.

Alternatives to Pyrex

Here are all the dishes available for beginners that they can use instead of pyrex glass.

Glassware may not be available for some and others may start now. Therefore, they may need something they can work with and have on hand.

Don’t worry, there might be at least one in your kitchen.


Frying pans can work the same way as pyrex glass dishes. If the pan is deep enough and the lid closes well.

You will also need to fry or sear the meat in a pan before placing it in the pan.

This extra step is necessary because an open fire cannot be used to heat a pan. Here, the casserole looks a lot like a Pyrex dish.

Terracotta pot

Clay pots work the same way as any small oven when it comes to heating. Therefore, they can do the same job as a Pyrex dish.

Moisture slides down the back into the shell as it evaporates. It is ideal for self-basting and for cooking turkeys. However, it is not very good for baking pies.

The design of the clay pot lid allows steam to rise while the dish is being prepared.

The humidity then condenses on the lid and then goes down again. This is called using the principle of convection to your advantage.

Today, terracotta pots are made glazed, so great care should be taken when choosing a heat source. An open fire is not a good source of heat. However, an oven is.

metal jar

Metal jars are a great alternative to glass pyrexpan. They can absorb heat much faster and retain heat much longer than pyrexpans.

For cooking, you can use the same techniques that apply when using a pyrexpan.

The soup pot works the same way as a soup pot.

Remember that you have to adapt a little to different recipes.


Braisers can cook almost anything fried or baked. The main difference is that the circumference of the sides of the pots are very different.

If you have a braiser, you can adapt the recipes with a little ingenuity.


Frying pans are great for baking or searing if desired. You can also cook different things in it if you need. You can also cook a roast in the oven on a skillet.

However, slow cooking and stewing are not things you can do in a skillet. There is also no cover, so you have to improvise there too.

Frying pan
